The statement "x < -7" is a mathematical inequality that describes a relationship between x and -7. In terms of a graph, it means that every value of x is less than -7. This can be visualized as a number line, where the point -7 is represented with a closed circle because it is not included in the solution set. To the left of this point, the line extends indefinitely, indicating that any value of x to the left of -7 satisfies the inequality.
